The pinout and layout is the same as the newer 3 and 4 PIs
It is necessary to connect the SCL and SDA pins to the GPIO on the PI
Also, connect the 5V and GND to the corresponding PI pins.
Also add the following on the config.txt file before booting:
ignore_lcd=0
Use the PWR_IN uUSB cable on the Display. Not on the PI. The PI fuse will blow.
